Description

Technical Field

[0001] The utility model relates to the technical field of building water supply and drainage, in particular to an anti-blocking structure for building water supply and drainage. Background Art

[0002] The drainage pipes in the building's water supply and drainage pipes may be blocked. Residents of residential buildings are often troubled by the blockage of drainage pipes, which affects the normal discharge of sewage. Due to lack of responsibility or carelessness, cotton threads, mop strips and other items are discharged into the sewage pipes. Due to the slow flow rate in the drainage pipes, cotton threads, mop strips and other dirt have a long residence time. Therefore, these dirts are mixed together to block the main sewage pipe, affecting the normal discharge of sewage from residents of one or several floors.

[0003] According to the "Anti-blocking device for building water supply and drainage" proposed in CN108708440B, the anti-blocking device for building water supply and drainage includes a main drainage pipe perpendicular to the building height and branch drainage pipes connected to the main drainage pipe on each floor, a U-shaped pipe is provided on one side of the branch drainage pipe connected to the main drainage pipe, a fixed cutter disc and a rotating cutter disc fitted on one side of the fixed cutter disc are provided at the bottom of the U-shaped pipe, a cutting blade or blade piece fixed on the inner wall of the U-shaped pipe is provided on the fixed cutter disc, a circular through hole is provided on the rotating cutter disc, and a ring-shaped cutter fitted on the side wall of the through hole is provided in the through hole; a power drum is provided in the main drainage pipe corresponding to the floors below the highest floor, and a push plate is hinged at equal intervals on the outer surface of the power drum, and the push plate is provided with a limit block fixed on the outer surface of the power drum on the front side of its own rotation direction; a fan blade driving plate is provided on the rotating cutter disc corresponding to the top floor. The present invention can ensure the effective acquisition of the power source, and has a good cutting effect on debris, and has a more comprehensive anti-blocking function.

[0004] Although the above-mentioned anti-blocking device for building water supply and drainage can break up the debris inside the U-shaped pipe, the bottom of the U-shaped pipe is provided with a fixed cutter disc and a rotating cutter disc attached to one side of the fixed cutter disc, which can easily affect the flow speed inside the pipe, thereby causing a large amount of debris to accumulate on the fixed cutter disc and the rotating cutter disc, thereby causing blockage.

[0005] Therefore, we propose an anti-blocking structure for building water supply and drainage to solve the problems in the above background. Utility Model Content

[0010] Preferably, a dredging valve is fixedly connected above one end of the U-shaped pipe close to the branch drain pipe, and the dredging valve is a solenoid valve.

[0011] Preferably, the upper end of the dredging valve is connected to a high-pressure water pipe, and a side closing valve is provided at the connection between the U-shaped pipe and the branch drainage pipe.

[0015] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0016] First, the utility model is used to solve the problem that the building water supply and drainage is easily blocked by an anti-blocking mechanism. It is connected between the branch drain pipe and the main drain pipe through a U-shaped pipe. Due to the special structure of the U-shaped pipe, water flow and small particle impurities will flow upward into the main drain pipe through the other end of the U-shaped pipe and be discharged, so that large particles of debris inside the branch drain pipe fall into the bottom of the U-shaped pipe to prevent the main drain pipe from being blocked. The knife roller is pushed downward along the telescopic cylinder into the bottom of the U-shaped pipe by the electric telescopic rod. The knife roller is driven by the servo motor to crush the large particle impurities trapped at the bottom of the U-shaped pipe and enter the main drain pipe with the water flow to be discharged to prevent the U-shaped pipe from being blocked. When no crushing is performed, the knife roller is retracted inside the telescopic cylinder to ensure the flow rate inside the U-shaped pipe to prevent it from being blocked.

[0017] Second, the utility model uses an electric push rod to push the sliding plate to slide inside the rectangular adjustment seat, so that the sliding plate opens and closes the branch drainage pipe, closes the branch drainage pipe, and then opens the solenoid valve above one end of the branch drainage pipe, connecting it to the high-pressure water pipe, and performing high-pressure flushing on the inside of the U-shaped pipe to prevent excessive accumulation of impurities after crushing and affecting drainage circulation.
